<p><b>This thesis examines high performance architectural tectonics through theoretical studies, design experiments, and through the design of two case study houses in Christchurch, New Zealand. The thesis focused on formulating a theoretical framework for a practice-focused, environmentally sustainable architecture by studying three key themes, specifically Architectural Tectonics, Contemporary Residential Architecture Detailing, and Energy Efficient Envelope Design.</b></p> <p>The integration of these three fields was undertaken to address the role of architectural design as the construction industry transitions to a net- zero carbon emissions future.</p> <p>Thermal tectonics takes a critical position towards the contemporary approach to residential architectural detailing, which increasingly intensifies the divergence between the tectonic expression of architectural junctions and the performance considerations of energy efficient envelope construction. This divergence results from a number of factors, including the increasing complexity of construction methods, the growing specialisation of building trades, and the increasing specialisation of architectural design.</p> <p>The project aims to tilt the existing aesthetic traditions of New Zealand residential architecture towards a language that performs better thermally. The thermal tectonic approach to architectural design intends to re-integrate the tectonic and performance considerations of the external envelope through a system-based approach to architectural design.</p> <p>Two case-study homes are developed through a tectonic framework that highlights the expressive potential of high performance construction systems. ‘Four Peaks House’ seeks to align a prefabricated SIP system with the vernacular typology of the Bach, developing a detail language that connects the building to place without the need for extensive low-performing glazing. ‘Gallery House’ explores the novel material of Hempcrete, demonstrating how exposing insulative materials can produce rich interior spaces.</p> <p>The design research was conducted through a series of design-led experiments focused on the six key principles of the Thermal Tectonic framework; anatomy, tectonic-stereotomic, space, place, detail and intersection, representation and ornamentation.</p> <p>This approach creates an explicit relationship between building elements and their thermal function, by using thermal simulation software to generate tectonic diagrams that describe how building elements are configured to express the thermal performance of a building. This provides architects with a critical tool for understanding how their design decisions can impact energy efficiency, while also allowing them to make design judgments that prioritise other factors such as aesthetic or material concerns. In addition, the research outcomes provide a direction for sustainable future practice that will ensure architectural ideas are translated into the high-performing language of our future built environment.</p>

Recently, the amount of attention paid towards convolutional neural networks (CNN) in medical image analysis has rapidly increased since they can analyze and classify images faster and more accurately than human abilities. As a result, CNNs are becoming more popular and play a role as a supplementary assistant for healthcare professionals. Using the CNN on portable medical devices can enable a handy and accurate disease diagnosis. Unfortunately, however, the CNNs require high-performance computing resources as they involve a significant amount of computation to process big data. Thus, they are limited to being used on portable medical devices with limited computing resources. This paper discusses the network quantization techniques that reduce the size of CNN models and enable fast CNN inference with an energy-efficient CNN accelerator integrated into recent mobile processors. With extensive experiments, we show that the quantization technique reduces inference time by 97% on the mobile system integrating a CNN acceleration engine.

<p><b>It is well known that many Maori cultural traditions and cosmological beliefs are anchored in a sea of knowledge associated with seafaring, navigation and the oceanic environment. Despite the loss of deep-sea voyaging, this thesis explores how nautical reflexes were still very influential on various modes of expression in Christian Maori architecture of three distinct Maori religious movements from the colonial and post-colonial periods. During this investigation, this thesis also identifies a relationship that can be found between the appropriation of nautical symbolism in Christian and Maori architecture.</b></p> <p>This relationship is examined on two levels: One, in terms of how Christian and Maori iconography has latent nautical meaning and secondly, how nautical symbolism in Christian Maori architecture is more signal than sculptural. The latter identifies the more powerful, metaphysical symbols in Maori architecture and spirituality which make Christian Maori architecture uniquely different from European Christian architecture. This thesis links these qualities in symbolic Christian maori architecture to the psychic and symbolic territories known to the navigator. In doing so, this thesis discovers how nautical symbols occupy a middle ground, an in-between area bridging the known with the unknown and examines their role as mediators between the present and the past; the individual and the collective.</p> <p>This thesis finally presents an architectural design which explores specific aspects of research. In doing so, the use of nautical symbolism and water-based pragmatism through architecture explores how such methods and expressions can influence and transform Western notions of knowledge or conventional notions of contemporary (terrestrial) architecture in New Zealand. To achieve this, nautical concepts from case study material are applied to a contemporary design project in order to open up architecture to its metaphysical dimension rather than focussing on the object (sculptural) that is frozen in time. As a result, this design also celebrates and revives the nautical instinct of Maori in terms of how it can offer new and meaningful ways to design architecture in oceania and New Zealand.</p>

<p>Over 70 years since it was completed, the house at 12 Fife Lane, Miramar, New Zealand’s first state house, looks unchanged. However, the intervening years have seen the failure of some state housing models, the deteriorating condition of others, as well as shifting and increasing housing demands. This thesis examines the urban and architectural design, and the subsequent redevelopment, both private and state-initiated, of post-war suburban state housing in New Zealand. The objective of this thesis is to understand through analysis of existing literature, case study fieldwork, and redevelopment examples, the evolving urban and architectural design of these areas and dwellings, which have arguably shaped the residential face of the nation. The outcomes of this thesis are a series of design strategies for the regeneration of post-war suburban state housing in New Zealand. The purpose of these regenerative design strategies is to address a range of significant issues that the Housing New Zealand Corporation faces, while acknowledging the remaining value of the original investment in post-war suburban state housing. The regenerative design strategies are developed from the earlier research, and are broken into three distinct, but inter-related topics. These are suburban environments, state properties, and state houses, and are examined through a specific design case study. The design case study articulates the potential of regeneration to address a number of issues which became apparent through the research. This thesis concludes that while state housing may never again signify in every sense the ‘very heart of the New Zealand dream’ (Ferguson, 1994, p.117), through regeneration it can, once again, be a certain benchmark for housing generally, and can continue to provide for the nation for at least another 70 years.</p>

William Smyth, unable to get work in a New Zealand museum, ran a commercial taxidermy business at Caversham, Dunedin, from about 1873 to 1911 or 1912. His two decades of correspondence with Thomas Frederic Cheeseman at the Auckland Museum provide a case study of Smyth's professional interaction with one of New Zealand's main museums. We have used this and other sources to paint a picture of Smyth's activities and achievements during a time when there was great interest in New Zealand birds but few local taxidermists to preserve their bodies. Besides the Auckland Museum, Smyth supplied specimens to various people with museum connections, including Georg Thilenius (Germany) and Walter Lawry Buller (New Zealand). Smyth was probably self-taught, and his standards of preparation and labelling were variable, but he left a legacy for the historical documentation of New Zealand ornithology by the large number of his bird specimens that now reside in public museum collections in New Zealand and elsewhere.
